Quantum mechanics and general relativity are the two pinnacles of 20th-century physics. In their respective fields, scientists have demonstrated time and time again how correct these theories are.

A new study published in Nature Physics introduces a theory of electron-phonon coupling that is affected by the quantum geometry of the electronic wavefunctions. The movement of electrons in a lattice ...

So, what exactly is quantum theory in chemistry? It’s basically the set of ideas that explain how atoms and molecules behave at a really, really tiny level. Think smaller than you can even imagine.

How much does a quantum measurement disturb what comes next? A team at TU Wien has discovered a surprisingly simple formula that sets a fundamental limit on the trade-off between measurement ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...
